To all whom'it may concern:

(Be it known that I, Tnums DE Youivc,

" 'Jr., a citizen of the United States, residing at v South Holland, the county of Cook and State ofIllinois, have invented a certain new and useful Improvement in Mechanism for Cleaning Excavator-Buckets, of which the following is a specification.

The invention relates to mechanism for excavating earth and particularly to traction ditch digging mechanism or ditchers' such as are well known in the art.

. into the conveyen for carrying the same' away, so that .the machine may work at high efficiency.- Y

The object of the invention is to provide means for cleaning all of the excavated earth out of each bucket, of such a mechanism,

' -rThe invention consists 'broadlyin mechan ism'for carrying out the foregoing objects which can be easily made and installed,

. anism pro er, are tilted first which is efficient in operation and'not readily liable to get ,out of order.

In the specific embodiment ofthe invention here shown it consists in a pivoted bottom for each bucket of the excavator mechmechanism adjacent to the conveyer, a can and the power for-driving the conveyer in such a way that the bucket 'bbttoms are in normal position during the digging operation to dump the .load from the ucket'into the conveyer and finally into contact with the scraper whereby as the bucket bottom passes over the scraper it is cor i ilpletely cleaned off into the conveyer. l

e. invention alsoconsists in details of 7 construction which will be hereafter described and claimed.

p The drawings illustrate only such parts of the ditcher proper as are necessary'to illustrate the invention. v

For convenience the'invention is shown applied to the well known Buckeye tract1on ditcher made by the company of the same-name, of Findlay,pOhio, but it Ina be applied to other similar machines wit out do arting from the invention. I

igure 1 is a side view artl sectional of a portion of .the main wheel lo 0 such a ditcher mounted on wheels 11 and 12 carried bythe supporting frame 13, the wheellO being-rotatable by means of power, appli'ed'through the shaft 15, to the wheel ll, which is, as shown, made the form of agear or pinion havingteeth meshing with the "circular rack Specification of Letters Patent. fihpplication filed June 8,1907. Serial No.37 8.016".

proper, combined with. a scraper to nolzl'mally hol h h V uprig t position t e counterweig t passing the slot 31 in the plate 25. The of each bucket bottom islimited in 16, secured to the wheel 10. On the wheel 10 are a plurality of buckets 18 each provided with a scraping or cutting edge 19. Each bucket has a tom 20 which hasheretofoi'e been stationa ith reference to the bucket 18' proper. I more properly earth which the articular bucket 'edge .19 is approaching so t t ebucket 18." The also form part of eac bucket The buckets are open on the circumference 24 of the wheel '10 said opening bein closed during the upward'travel of the bucl ted stationary plate 25.

at it may be scraped into] plates 23 of the wheel '10 ratenteasm, 7, 1908,-

Between each pair of buckets orin .front of each bucket is 'a' cutter or plow 22 designed to break up the t ets by the slot.- The result of the.

construction heretofore described, which is no part of this invention, is that as the Wheel 'isrotated in a counter clockwise direction the device cuts earth from the'trenchbelow the figure, scra es 'it into the buckets 18 which carry said irt up the plate 25 until its end 26 is reached after whichthe dirt, ifloo'se, falls over said edge onto the, conveyer belt 28 carried by wheel ,29'bywhich it is conveyed off to one side of the ditch. The conveyermec'h anism' is'sup orted on the beams 13 by the braces 30 as s own. w p p -Taking up now the features of th s nvention and the remainin figures of thedrawings, Fig. 2 isa sectional etail view on line 2'-2 of Fig. 1. Fig.-' 3 is a sectional detail plan view on line 33' of Fig. 1. 4 1s a per spective 'view of the' bucket bottom removed from the remaining parts and Fig, 5 is a pers ective detail view of the cam for operating t e bucket bottom or door.

In order to forcibly eject sticky earth such.

as gumbo soil from each bucket 18 as it asses the edge 26 of plate 25 each bucket ottom' 20 is ournaled on a rod or shaft 3 2 mounted in the plates 23 of-wheel 10 and is made of such a size that it may be tilted backward and forward. through the bucket proper between ulpright'and horizontal pos1- tionjasshown. I

trave the two extremes of its travel by stops 35 and 36. of 'plate 25 is aincam 38 and on the. o .posite side of the conveyer is a scraper 40 t e two. being so located as shown, that as the bottom' epending from each shaft I 32 is an arm 33 Y referabl'y counterwelghted d the bucket-bottom 20 1n Onthe wheel 10 adjacent to the end 26 I counterweight 33 of that particular bucket position before the bucket to carrying mechanism,

a -movable member within the budketadaptofoa loaded bucket reaches point or line 26 moved outof the bucket through the openand therefore all of the load which will fall ing and automatic ,means f out by gravity is free to and does fall down bottom as the load is discharged. into the conveyor 28, the depending arm or 4. In a conveyer a bucket open a bottom .for the load inthe bucket pivoted in such a position that as it is tilted it is moved out of the bucket through the opening and a scraperoadjacent to ,the position for discharging the loagl and automatic means .for tilting said bottom into contact, with said' scraper as the load is discharged.

5. In a trencher, a power carrying buckets adapted to di said buckets being open toward 51 the wheel,'means for closing said opening in the wheel in the portion of its circumference where elevation is taking place, a pivoted bottom foreach bucket adapted to support theload while elevating is taking place, a cam near" the upper end of said closing means adapted to be -enga ed by each bucket bottom as it reaches t e top of said closing means and tilt the bottom of the adjacent bucket toward the centerof the wheel and a scraper adapted to be then engaged bythe bottom of the bucket for the purpose set forth. Y Y

6. In a trencher, a power 'driven wheel carrying a plurality of earth digging buckets, a scfaper'adj acent to said whee a load supporting member within tomaticaneans for successively moving each of said members from load supporting position into contact with said scraper for the purposes set forth.

In witness whereof, I have hereunto subscribed my name in the presence'of two witnesses.

bottom engages cam '38 and as the wheel 10 continues to revolve, forcibly tilts the door or bottom through the bucket to the h0rizontal position, seen at the center of- Fig. 1, 10 in which position the bucket engages the sore er 40 and is cleaned onto the conveyor. As t e wheel 10 carries the door 20 on around its path of revolution the counterweight rct-urns the bottom of the bucket to normal which it belongs enters the ground again and'begins to dig.

What I claim as new and desire to secure by Letters Patent, is: a v 1. In mechanism of the class described a means for propelling sai ca mechanism ina predetermined path, a bucket attached to said carrying mechanism having an open face, parallel to :the path of travel of the carrying mechanism,

the earth 1 ed to normally support load within the bucket, and means for automatically moving said supporting member to a position where its load carrying face is slightly out of the 30 bucket throu h said open face and is then parallel with t e path of travel of the bucket.
